Just don't confuse my speculation with what P&F say (it did not tell you to sell back then and it did tell you to go long safely at 240).
I just had to warn people because the chart was saying something - it could have gone really bearish (weren't for Gemini hype) and you know it.

We present all the data and it is up to everyone to interpret them - it is very difficult to be emotionless all the time.

P&F is very powerful at everything except catching the knife and selling the top (basically it has a very good indicator based solely on P&F - trendline oscillator- but is it very difficult to implement, something like the RSI).*

I believe though that with the RSI analysis plus other classical indicators, it is possible to use it with almost 100% success.

I am building tools that people have to pay A LOT in order to use (see dorsey wright, updata, stockcharts, bull's eye broker, etc).

There are very big & serious Hedge Funds who make a fortune with algorithmic trading I can assure you!

Market analytics is very powerful tool whether people like it or not and they work in low volume markets like BTC too.

It is much more difficult to do so but possible.

Cheers.

*EDIT: I forgot Price Objectives - very powerful tool too, even if the price does not meet the target, this fact gives you another indication of momentum (it is bearish not to meet a bullish PO etc.)
